M_Boats: Running halyards to cockpit

Has anyone run their halyards aft on their M17? I'd intended to use a pair of double pulley deck organizers to make the turn aft but am finding they fit awkwardly between the hand rails and hatch slides on the cabin roof. I'm thinking I have room for only a single cheek block on each side of the cabin roof. I had hoped to run halyards and reefing lines to the cockpit. I'm now thinking maybe I'll only run the Halyards back, and put the reefing line on the boom. Any input? I also think if I do boom mounted reefing line I might use a hook on a line turning through a cheek block to a cleat on the boom. Mitch M17 656 Grace.
